Cubitus valgus deformity

Introduction to elbow valgus deformity Elbow joints with an angle of more than 20° are called elbow valgus. Elbow valgus deformity after elbow trauma is less common than elbow varus. Most patients come to seek treatment for secondary elbow ulnar neuritis. The cause of the disease is mostly caused by poor treatment of the elbow bone and joint. Patients with elbow valgus without elbow joint dysfunction and pain symptoms are generally not required to be treated, but follow-up should be observed and further treatment should be taken as appropriate. basic knowledge The proportion of illness: 0.001% Susceptible people: no specific population Mode of infection: non-infectious Complications: neuritis

Elbow valgus deformity etiology

Causes:

The cause of the disease is mostly caused by poor bone and joint injury, and the treatment effect is not good. The elbow joint angle of more than 20° is called elbow valgus.

Unbalanced osteophyte development (25%):

Children with supracondylar fracture of the humerus and distal radius fracture have not been reset after injury or the ideal reduction is not corrected in time. This is the most common cause of elbow valgus deformity, mainly due to the medial and lateral distal humerus ( Osteophytes) caused by uneven growth and development.

Poor treatment after injury (20%):

Children with internal or external humeral fractures failed to be restored or reset poorly, which may cause temporomandibular closure of the external humerus or ischemic necrosis. The elbow valgus caused by the fracture of the humerus is due to internal iliac crest. Caused by excessive growth.

Other factors (18%):

Other factors include dislocation of the elbow without unreset or poor reduction; after the humeral head resection, the important mechanical obstruction of the proximal humerus disappeared after the humeral head resection, resulting in abnormal biomechanics of the elbow joint and forearm.

Elbow valgus deformity prevention

The prevention of this disease is mainly to early detection, early diagnosis, early treatment, and some patients who need surgical reduction after fracture or dislocation should be treated promptly, especially for children with internal and external humeral fractures. To prevent the occurrence of this disease if the reset is not timely.

Elbow valgus deformity complications Complications

Delayed ulnar neuritis.

Elbow valgus deformity symptoms Common symptoms Elbow joint deformity elbow valgus angle increase elbow joint can not flex

When the normal elbow joint is fully extended, there is a mild valgus male about 10° and a female about 15°. This valgus angle is called a carrying angle. If this angle is increased, the forearm is too abducted, called the elbow valgus deformity. The most common cause of elbow valgus is a supracondylar fracture of the humerus and a distal radius fracture in children without decompression or reduction. The fracture of the medial or lateral humerus in children has not been reset or poorly restored, the humerus is too early, or ischemic necrosis. Elbow valgus can be caused by dislocation of the elbow without unreset or poorly reset.

Elbow valgus deformity examination

Because the disease is generally easy to make a diagnosis based on the appearance of the spring appearance, it is less likely to use the auxiliary examination. Clinically, some patients with insignificant performance can be diagnosed by X-ray examination.

X-ray examination of the elbow: the angle of the elbow joint is increased or decreased, and even the negative angle may have osteoarthritis.

Diagnosis and diagnosis of elbow valgus deformity

When the elbow joint is straight, the elbow valgus angle can be increased by more than 30°; the elbow joint activity generally has no obvious obstacle; the joint surface damage of the late elbow joint can cause pain. The patient with severe valgus is pulled by the ulnar nerve under high tension. In the state or after trauma, due to ulnar nerve adhesion and frequent friction, delayed ulnar neuritis may occur and ulnar nerve injury may occur.

The effect of treatment of traumatic history is poor, and the angle of the carrier is increased. X-ray examination shows the angle of the carrier and measures the angle.
